Solution:

Step-1: Subtract 4.3 both sides.

x/5 + 4.3 = 12.4
=> x/5 + 4.3 - 4.3 = 12.4 - 4.3
=> x/5 = 8.1

Step-2: Use cross multiplication to find x.

x/5 = 8.1
=> x = 8.1 x 5
=> x = 40.5

Hence, the value of x is 40.5.

Tracie rides the bus home from school each day. The graph represents her distance from home relative to the number of minutes si

natali 33 [55]

Answer:

1. Tracie's bus travels towards her home at an average speed of $\frac{1}{2}$ miles per minute.

Step-by-step explanation:

From the graph, we see that,

X-axis represents the time (in minutes) and the Y-axis represents the distance from home (in miles).

Also, the graph of the function is decreasing by 1 miles for every 2 minutes.

That is, the distance from home is decreasing as the time increases.

That is, the bus is getting closer to the home.

Further, as the distance is decreasing by 1 mile for every 2 minutes.

Thus, the rate of decrease is $\frac{1}{2}$ miles per minute.

As we know, $Speed=\frac{Distance}{Time}$

So, the slope represents the speed of the bus travelling towards home.

That is, 'Tracie's bus travels towards her home at an average speed of $\frac{1}{2}$ miles per minute'.
